Yes, provided that "adirectory" exists and you have write permission.
It won't make a directory for you. Same applies to open('adirectory/
db', 'wb')

Ensure that adirectory exists, and try it again. If that fails, try
the open() -- you may get a more informative error message.

No. However, try that and remember what happens.
